Here are the solutions to your geometry problems.
1. KLMN is a parallelogram. Calculate the size of the interior angles.
In a parallelogram, consecutive angles are supplementary (add up to $180^\circ$).
Given $\angle N = 5x - 12^\circ$ and $\angle M = 3x + 18^\circ$.
Step 1: Set up the equation for consecutive angles.
$$ \angle N + \angle M = 180^\circ $$
$$ (5x - 12) + (3x + 18) = 180 $$
Step 2: Solve for $x$.
